Tranexamic Acid Tablet IP 500mg is a Schedule H prescription medicine that plays a crucial role in the management of excessive bleeding. It is widely prescribed for heavy menstrual bleeding (menorrhagia), nosebleeds, and bleeding associated with dental procedures in patients with clotting disorders. Since this medication directly affects blood clotting, it must always be taken strictly under the supervision of a qualified physician.
What is Tranexamic Acid and How Does it Work?
Tranexamic acid is an antifibrinolytic agent, meaning it prevents the breakdown of blood clots. Normally, the body produces fibrinolytic enzymes that dissolve clots once healing begins. However, in conditions of excessive bleeding, this can cause blood loss to worsen. Tranexamic acid works by blocking the activation of plasminogen to plasmin, thereby stabilizing blood clots and effectively reducing bleeding.
This mechanism makes Tranexamic Acid Tablet IP 500mg an essential therapeutic option in managing gynaecological bleeding, post-surgical bleeding, and hereditary bleeding disorders.
Indications for Tranexamic Acid Tablet IP 500mg
The primary indications for this medicine include:
- Menorrhagia (Heavy Menstrual Bleeding): Helps reduce excessive blood loss during menstrual cycles.
- Epistaxis (Nosebleeds): Used in recurrent or severe bleeding.
- Dental Extraction Bleeding: Especially useful in patients with clotting disorders.
- Surgical Procedures: Sometimes prescribed postoperatively to minimize blood loss.
- Other Bleeding Disorders: As advised by physicians for hereditary conditions such as hemophilia.
Recommended Dosage and Administration
The dosage regimen must always be prescribed by a doctor, as it depends on individual needs, medical history, and renal function.
- For Menorrhagia (Heavy Periods):
Commonly prescribed at 1000–1500 mg (2–3 tablets of 500mg), taken three times daily for a maximum of 4–5 days during menstruation. - Timing of Use: Tablets should be taken only after menstrual bleeding has started. They are not meant to be taken preventively before the period begins.

If bleeding persists or worsens despite treatment, it is vital to consult the prescribing physician immediately.

Major Warnings and Possible Side Effects
Patients and caregivers must be aware of potential risks:
- Thromboembolic Risk: Watch for signs such as sudden chest pain, shortness of breath, leg swelling, or stroke-like symptoms. Immediate medical attention is required.
- Vision Problems: Rarely, patients may experience blurred vision or impaired color perception. Discontinue immediately and consult an ophthalmologist.

Drug Interactions: Medicines to Avoid
Tranexamic acid may interact dangerously with other medications. Inform your doctor if you are taking:
- Hormonal contraceptives: Increase clot risk.
- Other antifibrinolytic agents (e.g., aminocaproic acid): Additive clotting effect.
- Procoagulant medications: Such as Factor IX complex or Anti-Inhibitor Coagulant Concentrates.
- Fibrinolytic drugs: Tranexamic acid counteracts clot-dissolving medicines like alteplase.
- Oral Tretinoin (All-Trans Retinoic Acid): May enhance clot formation.
Tranexamic Acid Use in Pregnancy and Lactation
